Singapore's former prime minister Lee Kuan Yew's condition has "deteriorated", the Prime Minister's Office (PMO) said in an update on Wednesday, 18 March.

He remains critically ill in the Intensive Care Unit, the PMO added.

On Tuesday, the PMO had said that he was on antibiotics and that doctors "are closely monitoring his condition".

An earlier update on Friday, 13 March said Lee Kuan Yew's condition was largely unchanged from a 28 February update. At that time, a statement from the PMO revealed he was sedated and remains on mechanical ventilation. Doctors also administered antibiotics.
